Frequently asked questions
Is this PNG to AVIF converter free?
Yes — completely free with no limits, no signup, and no watermarks. Convert as many PNG images to AVIF as you like.
Are my images uploaded to a server?
No. Conversion happens locally in your browser using the HTML5 Canvas API, so your images never leave your device. Only formats that browsers can't natively process are converted via our encrypted server API, and those files are deleted immediately.
Will converting PNG to AVIF reduce image quality?
You stay in control: the quality slider (10–100%) lets you choose the balance between sharpness and file size. At 90%, quality loss is visually invisible for most photos.
Can I convert multiple PNG files to AVIF at once?
Yes. Drop or select as many files as you need — each is converted and listed individually, and you can download them all together as a ZIP. For mixed input formats, use our Bulk Image Converter.
Does it work on mobile phones?
Absolutely. ToolsCrow is mobile-first: the converter runs entirely in your phone's browser on Android and iOS — no app installation needed.
